I. Load Index and Speed Rating
The two- or three-digit number is
the tire’s load index, the maximum
load a tire can carry at the speed
indicated by its speed symbol at
the maximum inflation pressure.
The higher the number is, the
greater the load carrying capacity.
The letter symbol denotes the
speed at which a tire is designed
to be driven for extended periods
of time. (Ratings are listed below.)*The letters ZR may be used on tires
with a maximum speed capability over
149 mph and will always be used on
tires with a maximum speed capability
over 186 mph.
J. M+S Marking
This marking indicates the tire
has some mud and snow capabili-
ties and is designed for all-season
use.Tire Size

WARNING
Your SUZUKI is equipped with
tires which are all the same type
and size. This is important to
ensure proper steering and han-
dling of the vehicle. Never mix
tires of different size or type on
the four wheels of your vehicle.
Mixing tires could cause you to
lose control while driving which
may lead to an accident. The size
and type of tires used should be
only those approved by SUZUKI
Motor Corporation as standard or
optional equipment for your vehi-
cle.

NOTE:
The tire inflation pressure will change
due to changes in atmospheric pres-
sure, temperature or tire temperature
when driving. To reduce the chance that
the low tire pressure warning light will
come on due to normal changes in tem-
perature and atmospheric pressure, it is
important to check and adjust the tire
pressures when the tires are cold. Tires
that appear to be at the specified pres-
sure when checked after driving, when
the tires are warm, could have pressure
below the specification when the tires
cool down. Also, tires that are inflated to
the specified pressure in a warm
garage may have pressure below the
specification when the vehicle is driven
outside in very cold temperature. If you
adjust the tire pressure in a garage that
is warmer than the outside tempera-
ture, you should add 1 psi to the recom-
mended cold tire inflation pressure for
every 10°F difference between garage
temperature and outside temperature.Measuring Air Pressure
Use the following steps to achieve
proper tire inflation:
1) Identify the recommended tire pres-
sure on the vehicle’s Tire and Load-
ing Information Label or in the
owner’s manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge,
measure the tire inflation pressure
by pressing the tire gauge firmly
onto the valve to get a pressure
measurement. Remember that
inflation pressures should be
checked when the tires are “cold”,
meaning before they have been
driven one mile or after sitting for
three hours or more allowing the tire
to cool to ambient air temperature.
4) If the air pressure is too high, slowly
release the air by pressing on the
tire valve stem with the edge of the
tire gauge until you reach the cor-
rect pressure.
5) If the air pressure is too low, fill the
tire with air at a service station until
it reaches the recommended pres-
sure.
6) Make sure all tires have the same
air pressure (unless the owner’s
manual indicates otherwise).
WARNING
 Air pressures should be
checked when the tires are cold
or you may get inaccurate read-
ings.
 Check the inflation pressure
from time to time while inflating
the tire gradually, until the spec-
ified pressure is obtained.
 Never underinflate or overin-
flate the tires.
Underinflation can cause
unusual handling characteristics
or can cause the rim to slip on
the tire bead, resulting in an acci-
dent or damage to the tire or rim.
Underinflation can also cause
tires to overheat, leading to tire
failure.
Overinflation can cause the tire
to burst, resulting in personal
injury.
Overinflation can also cause
unusual handling characteristics
which may result in an accident.

Tire Inspection
Inspect your vehicle’s tires at least
once a month by performing the fol-
lowing checks:
1) Measure the air pressure with a tire
gauge. Adjust the pressure if nec-
essary. Remember to check the
spare tire, too. Refer to the “Mea-
suring Air Pressure” section.

(1) Tread wear indicator
(2) Indicator location mark
2) Check that the depth of the tread
groove is more than 1.6 mm (0.06
in.). To help you check this, the tires
have molded-in tread wear indica-
tors in the grooves. When the indi-
cators appear on the tread surface,
the remaining depth of the tread is1.6 mm (0.06 in.) or less and the
tire should be replaced.
3) Check for abnormal wear, cracks
and damage. Any tires with cracks
or other damage should be
replaced. If any tires show abnor-
mal wear, have them inspected by
your SUZUKI dealer.
4) Check for loose wheel nuts.
5) Check that there are no nails,
stones or other objects sticking into
the tires.
WARNING
Hitting curbs and running over
rocks can damage tires and affect
wheel alignment. Be sure to have
tires and wheel alignment
checked periodically by your
SUZUKI dealer.
WARNING
Your SUZUKI is equipped with
tires which are all the same type
and size. This is important to
ensure proper steering and han-
dling of the vehicle. Never mix
tires of different size or type on
the four wheels of your vehicle.
The size and type of tires used
should be only those approved by
SUZUKI Motor Corporation as
standard or optional equipment
for your vehicle.
CAUTION
For intelligent All Wheel Drive (i-
AWD) models, replacing a tire
with one of a different size, or
using different brands among the
four tires can result in damage to
the drive train.

Uniform Tire Quality Grading
The U.S. National Highway Traffic
Safety Administration has developed a
grading system for evaluating the per-
formance of passenger car tires. The
following information will help you
understand the grading system, which
applies to vehicles sold in the U.S.
Consult your SUZUKI dealer or tire
retailer for help in choosing the correct
replacement tires for your vehicle.
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Tempera-
ture A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All Passenger Car Tires Must Conform
To Federal Safety Requirements in
Addition To These GradesTreadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course. For example, a tire graded 150
would wear one and one-half (1 1/2)
times as well on the government course
as a tire graded 100. The relative per-
formance of tires depends upon the
actual conditions of their use, however
and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in
road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
Replacing the wheels and tires
equipped on your vehicle with
certain combinations of aftermar-
ket wheels and tires can signifi-
cantly change the steering and
handling characteristics of your
vehicle. Oversized tires may also
rub against the fender over
bumps, causing vehicle damage
or tire failure. Therefore, use only
those wheel and tire combina-
tions approved by SUZUKI Motor
Corporation as standard or
optional equipment for your vehi-
cle. For information regarding the
specified tires, refer to the Tire
Information Label located on the
driver’s side door pillar or the
“SPECIFICATIONS” section.
CAUTION
Replacing the original tires with
tires of a different size may result
in false speedometer or odometer
readings. Check with your
SUZUKI dealer before purchas-
ing replacement tires that differ in
size from the original tires.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and
does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.

INSPECTION AND MAINTENANCE
80J23-03E
Temperature – A, B, C
The temperature grades are A (the
highest), B and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C corre-
sponds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.Tire Rotation
54G114
To avoid uneven wear of your tires and
to prolong their life, rotate the tires as
illustrated. Tires should be rotated as
recommended in the periodic mainte-
nance schedule. After rotation, adjust
front and rear tire pressures to the
specification listed on your vehicle’s
Tire and Loading Information Label.
WARNING
The temperature grade for this
tire is established for a tire that is
properly inflated and not over-
loaded. Excessive speed, under-
inflation or excessive loading,
either separately or in combina-
tion, can cause heat buildup and
possible tire failure.
WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after a time. The wheel could
come off and cause an accident.
When you change a wheel,
remove any rust or dirt from
places where the wheel attaches
to the vehicle. In an emergency,
you can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush later,
if you need to, to get all the rust
or dirt off.

Compact Spare Tire (if equipped)
54G115
(1) Wear indicator
(2) Indicator location mark
Your vehicle comes equipped with the
compact spare tire. The compact
spare is designed to save space in
your storage area, and its lighter
weight makes it easier to install if a flat
tire occurs. It is only intended for tem-
porary emergency use, until the con-
ventional tire can be repaired or
replaced. The inflation pressure of the
compact spare tire should be checked
at least monthly. Use a quality pocket-
type inflation pressure gauge and set
at 420 kPa (60 psi). At the same time,
check that the tire is stored securely. If
it is not, tighten it.Note that two or more compact spare
tires should not be used on one vehi-
cle simultaneously.
WARNING
The compact spare tire and wheel
are intended for temporary emer-
gency use only. Continuous use
of this spare can result in tire fail-
ure and loss of control. Always
observe these precautions when
using this spare:
 Your vehicle will handle differ-
ently with this temporary spare.
 Do not exceed 80 km/h (50 mph)
speed.
 Replace this spare with a stan-
dard tire and wheel as soon as
possible.
 Use of this spare will reduce
ground clearance.
 Recommended air pressure for
this spare is 420 kPa (60 psi).
 Do not use tire chains on the
compact spare. If you must use
tire chains, rearrange the
wheels so standard tires and
wheels are fitted to the front
axle.
(Continued)
WARNING
(Continued)
 The compact spare tire has a
much shorter tread life than the
conventional tires on your vehi-
cle. Replace the tire as soon as
the tread wear indicator
appears.
 When replacing the compact
tire, use a replacement tire with
the exact same size and con-
struction.
CAUTION
For intelligent All Wheel Drive (i-
AWD) models, driving with an
underinflated compact spare tire
or over 80 km/h (50 mph) while
using a compact spare tire can
result in damage to the drive
train.
